On the possible contributions of two nearby blazars to the NGC 4151 neutrino hotspot
Anastasiia Omeliukh, Samuel Barnier, Yoshiyuki Inoue
The origin of the high-energy astrophysical neutrinos discovered by IceCube remains unclear, with both blazars and Seyfert galaxies emerging as potential sources. Recently, the Ice…
Multi-epoch X-ray spectral analysis of Centaurus A: revealing new constraints on iron emission line origins
Toshiya Iwata, Atsushi Tanimoto, Hirokazu Odaka +3
We conduct X-ray reverberation mapping and spectral analysis of the radio galaxy Centaurus A to uncover its central structure. We compare the light curve of the hard X-ray continuu…
The possibility of multi-TeV secondary gamma rays from GRB221009A
Oleg Kalashev, Felix Aharonian, Warren Essey +2
The brightest gamma ray burst (GRB) ever observed, GRB221009A, produced a surprisingly large flux of gamma rays with multi-TeV energies, which are expected to be absorbed in intera…
Neutrinos and gamma rays from beta decays in an active galactic nucleus NGC 1068 jet
Koichiro Yasuda, Nobuyuki Sakai, Yoshiyuki Inoue +1
We show that TeV neutrinos and high-energy gamma rays detected from the nearby active galaxy NGC 1068 can simultaneously be explained in a model based on the beta decays of neutron…
ALMA Confirmation of Millimeter Time Variability in the Gamma-Ray Detected Seyfert Galaxy GRS 1734-292
Tomonari Michiyama, Yoshiyuki Inoue, Akihiro Doi +4
GRS 1734-292 is a radio-quiet galaxy, exhibiting neither intense starburst nor jet activities. However, Fermi-LAT detected this object in the GeV band. The origin of non-thermal ac…
Upper Limit on the Coronal Cosmic Ray Energy Budget in Seyfert Galaxies
Yoshiyuki Inoue, Shinsuke Takasao, Dmitry Khangulyan
The IceCube collaboration has reported possible detections of high-energy neutrinos from nearby Seyfert galaxies. While central hot coronae are proposed as the primary neutrino pro…
